TYPE-W ITING MACHIN E.

SPECIFICATIQN forming part of Letters ramlilo. 698,318, dated A rnea-woaApplication filed May 29, 1901.;

To all whom it may conceiva- Be it known that I, WILLIAM P. QUENTELL,

a citizen of the United States, residing at Manhattan borough, New Yorkcity, county of New York, and State of New York, have invented new anduseful Improvementsin Type- Writing Machines, of which the following isa specification.

This invention resides-in certain novel features of construction setforth in the following specificationand claims and illustrated in theannexed drawings, in which- Figure 1 is a plan View of the machine. Fig.2 is a side elevation of Fig. 1. Fig. 3 is a section along a; :20, Fig.2. Fig. 4 is a section along y y, Fig. 2. Fig. 4 is a plan view of thetype-wheel-driving segment. Fig. 5 is a sectional side elevation of Fig.1, showing Fig. 6: Fig. 7 shows a the type-wheel in the art of printing.is a section along 2 2, Fig. 5. plan view of the machine with a type-armhavingperforations or engaging portions by which 1 such arm can -.be notonly stopped, but also The reference-numeral 6 denotes suitable risersor supports for the centers of a shaft 16. This shaftl6'is convenientlyformed in two sections, which when'in the machine the said sections havetheir inner ends joined by or mounted in a frame 30, which can beprovided with suitable hub or recessed parts for seating the inner endsof the opposite see- On the shaft 16 are sleeves or bearings 17, Fig. 1,of levers or arms 19, Fig. 2,-eonnected by link 19 with lever or ratherbail 18, Figs. 5 and 6, actuated by the key-levers. Two levers 19, withtheir respective parts, are shown; but the description of one explainsthe other. As one lever 19 orthe other is actuated it strikes a shoulder20, Fig. 4, on shoulder or disk 21, Figs. 1 and 2, so as to oscillatethis piece with SerialNo. 62,410. (N oinodel.)

rock shaft or sleeve22, carrying arm 23, with segment 24 engaging gear25 of the typewheel or its shaft.v As the gear 25 is oscillated one wayor another, with disk 48 having connection by means of pin 26 with thetype-wheel, the latter is turned or set to bring a required type tothe'printing position.

The type-wheel shaft 27 is shown with a sleeve" 29 rotating with gear 25and carried by frame 30, vibrated, as presently explained, for theprinting stroke. With this sleeve rotates a pinion 37, engaging asegment 36, having an arm 39, adapted to be stopped or arrested by thepins 18, each of which is lifted or moved to stopping position by itsrespective key-lever when depressed.

When a key-lever is depressed, it lifts a pin and actuates levers Band19, which latter rotate the type-wheel and pinion 37, so as to swingstop-arm 39 until stopped by the pin,

which has been raised or brought by its respective key to arrestingposition. After the rotation of the type-wheel is stopped the continuedpull of levers 10 and 18 causes frame 30 toiswingso-as to dipor strikethe typewheel againstthe platen.

The arm39 and row 'of pins 18, extending each side of thecenter line ofthe machine, are shown not parallel with one another, but in curvedrelation to one another. It is evident that thelarm and; pins must be soarranged that the wheel can turn. more or less to bring the requiredtype to printing position before the arm or the rotation is stopped. Thearrangement shown ofa straight row of pins and a stop Qarm with curvedparts or branches or curved face'tocontact With the pins extendingtoward each side of the machine has been found compact 5 but of courseforming such inner end, are adapted to lift or release a locking-bail43, which is adapted to engage hook 4.4 or a depression in said hook,Fig. 5, and prevent premature tiltingof the type-wheel. On a key beingdepressed its pin 18' starts rising, and the respective lever 19 beingactuated by link 19 and arm 18 will rotate the type-wheel, such rotatingbeing stopped at the proper moment by arm 39, swinging right or left,striking the raised pin. The inner end of the key lifting or unlockingthe stop 43 at the proper moment further depression of the key, with theresulting downward pull of link 19', will draw the frame 30, with wheel1, to the platen. When the stop or bail 43 engages the arm or dependingpart 44 of frame 30, the latter is locked against vibration, so that thetype'wheel cannot dip.

The spacing arrangement may be of any suitable kind, such as rack 47 anddog 46, actuated by arm 50, which latter is moved by the key-levers.

The pinion 37 is shown brought close to the center of vibration or shaft16 of the typewheel, so that the printing stroke will cause but slightvibration or shift of the pinion and loss of mesh with the segment orgear 36 is avoided. The segment 36, with its arm 39, has its pivot orfulcrum independent of the typewheel-carrying frame 30, and such pivotcan be mounted or carried on a comb-plate or any suitable riser or partof the machine.

The ribbon or inking device is not shown, as any suitable ink-rollerwill do.

The case-shifting movement of the typewheel or its shaft 27 can beeffected by a lever-arm 55, fulcrumed at 56.

The arm 48 is secured to a suitable part of the machine, and duringprinting the toothed disk 48 engages this arm to lock the type wheel orsecure accuracy.

The levers 19 when at rest or in normal position lie against stops orscrews on frame 30, and a stop 66 limits the upward swing of thetype-wheelthat is, the backward swing of arm let. These stops can bereadily made adjustable, for example, by forming them of screws.

In order to lock the type-wheel when arm 39 has struck a stop and thewheel begins to dip, a lever, as shown at 67, Fig. 2, can be applied.This lever or blade is made to normally drop or spring to engagementwith disk 48 of wheel 1, Fig. 5; but when this wheel or its frame 30 israised or in normal position the blade 67 is held out of action to havewheel 48 and segment 1 rotate. When, however, frame 30 begins to dip,the blade 67 is carried away from stop 68, so that the blade will engagethe toothed wheel 48. The stop 68 is readily formed by a screw placed ina bridge or cross-piece 69.

When arm 39 strikes a stop or pin 18' and arrests the axial motion ofthe wheel, a rebound may occur in case the key is struck very hard. Suchrebound occurring just at the moment that frame 30 begins to tilt, thelocking lever or blade 67 drops into a space or notch in disk 48, thuspreventing the rebound being communicated to type-wheel 1, and when thedisk 48 engages arm 48 the type-wheel is held against oscillation, sothat a neat print is assured or blurring avoided.

A modification is shown in Fig. 7 by which a rebound on the arm 39striking a pin 18 can be prevented. According to this modifiedconstruction the stop-arm 39 has a beveled or inclined edge or face 39,and on coming against a pin said arm or its bevel slides or rides up ontop of the raised pin until such pin locks or engages an eye or suitablepart 70 of the arm to lock the latter and prevent rebound. The arm 39 isthus locked until the key is released or the pin 18 drops. The arm 39can yield or spring so as to ride with its beveled face over or riseonto an elevated stop-pin, or such stop-pins can each have a spring oryielding support 10 resting on its respective finger-keys, so as to snapat the proper moment into a perforation or locking part of the stop-arm.The toothed disk 48 with pawl 67 at the type-wheel and the lookingarrangement for preventing rebound of the stop-arm when striking araised stop-pin can be used separately or can be applied together in onemachine. It maybe noted, how ever, that a lock preventing rebound of thestop-arm has been found sufficientin making practical tests. M

As seen in Fig. 7, the beveland locking eyes do not extend entirely upto the pivot-point 36, since in practice it has been found that theinner portions of arm 39, having to travel only a comparatively shortdistance before being arrested by a stop 18, do not rebound or atany-rate so slightly as not to require a lock.
